Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503092, here are decompositions:

31 + 31503061 = 31503092
139 + 31502953 = 31503092
151 + 31502941 = 31503092
211 + 31502881 = 31503092
331 + 31502761 = 31503092
349 + 31502743 = 31503092
433 + 31502659 = 31503092
661 + 31502431 = 31503092

Showing the first eight; more decompositions exist.
